SPECIFICATION forming part of Letters Patent No. 382391, dated May 1, 1888.

Serial No. 231,519. (No model.)

.To all whom, i may concern.-

Be it known that I, JOSEPH Novns KnLsnn, of Antrim, in the county of Hillsborough and State of New Hampshire, have invented cer tain new and useful Improvements in Spools or Bobbins, of which the following is a specifica ion.

My invention relates to spools or bobbins, and particularly to that class or kind of such d ylces as are employed in the manufacture of si In the construction of spools or bobbinsfor the purpose mentioned, it is desirable, among other'things, that the article should be light 1n weight.; that the barrel should be strong, so as to withstand the crushing tendency of the threads wound thereon; that the heads should be smooth and durable in order to avoid catchlng upon and breaking or abrading the threads, and to resist wear and liability of being chipped or otherwise damaged in handling, and that the pool as a whole should be cheap of construcion.

It -is the object of my invention to meet these requirements in a spool or bobbin for the manufacture of silk,which I do by the improvements hereinafter described and claimed.

Reference is to be had to the accompanying drawings and to the letters of reference marked thereon, forming a part of this specification, the same letters indicating the same parts wherever they occur.

Of the drawings, Figure l represents a lon gitudinal vertical section of a spool or bobbin embodying my invention. Fig. 2 represents a like View of a modied construction of the same. Fig. 3 is a perspective View of the invention, the two parts comprising the barrel being separated.

In the drawings, A indicates the barrel of the spool or bobbin, composed of any suitable material, preferably of wood, and madein two parts, a b, the division being at the central point longitudinally of the barrel, and the parts being hollowed or bored out from the division line or meeting ends toward the outer or head ends of the barrel, the hollow or bore in each part being of rounded or conical form toward thehead or outer end, while it may be ency of the material wound thereon, such remaining material operating on the principle of an arch; and to secure the form of bore dei scribed with facility and eXactness the division of the barrel is made. y

As a means of uniting the two parts of the barrel, one partsay that indicated by amay be turned down at its inner end, as at c', and a corresponding enlargement, d, made in the bore of the other part, b, and the two parts `joined and held by friction; or, if desired, cement may be employed as well.

In some instances I may employ a light metallic ring, e, in the interior of the barrel in order to further sustain the latter against crushing strain. This ring can readily be inserted in the barrelas, for instance, in the end of part abefore the parts a and b are united for use.

B B represent the bobbin-heads, composed of that class of compressed paper-pulp known asleatherboard.7 Theseheadsarescrewed, cemented, or otherwise properly secured on the turned-down ends f f of the barrel B, as shown in Figs. 1 and 2, and in addition to being strong and durable, so as to withstand Wear and not be easily chipped, nicked, or otherwise damaged in handling, as when they are thrown together in a basket or other receptacle, they can be made with a very smooth polished surface, so as not to be liable to catch upon and break or abrade the thread 5 and, furthermore, as the material mentioned. is quite light of weight, this advantage also is gained.

By constructing aspool-bobbin in the man ner described and using therein the material specified I am enabled to attain the objects recited at the outset lof this specication; and though I have been particular :in describing the form and arrangements of the several parts constituting my improvements, it is obvious that these may be varied within the limits-of mechanical skill Without departing from the nature or spirit of my invention.

Having thus described my invention, what I cla-im is- 1. A spool or bobbin having a hollow barrel constructed inV two parts united at a central point, the form of the bore toward Vthe ends of the barrel bei-ng conical or rounded, substantially as and for the purposesset` forth.

2. A spool or bobbin having a hollow barrel constructed in two parts united at a central point, the form of the hollow or bore being conical or rounded toward the ends of the barrel and enlarged or of substantially uniform diameter through the middle portion of its length, substantially as and for the purY poses set forth.

3. A spool or bobbn having ahollow barrel of wood constructed in two parts united at a central point, themeeting ends overlapping, as set forth, in combination with a metallic sustaining-ring, e, extending around within JOSEPH NOYES KELSEA.
